The effects of the surface UV light application using continuous system on the quality of kaymak (Turkish cream)
No full textKaymak ülkemizde uzun yıllardır geleneksel yöntemle üretilmekle birlikte, son yıllarda ise süt işletmelerinde direkt kremadan üretilmektedir. Geleneksel kaymak üretiminde yüzeyde kaymağın toplanması ve sertleşmesi ve paketlenmesi aşamalarında kaymak yüzeyi kontaminasyona oldukça açıktır. UV ışık teknolojisi, gıdalarda mikrobiyal inaktivasyon için kullanılmaktadır. Ancak, mikrobiyal inaktivasyon sağlanırken ürünün fiziksel, kimyasal ve duyusal kalitesini de koruması önemlidir. Bu çalışmada kaymakta UV ışık teknolojisinin kaymak kalitesine etkisi araştırılmış ve kısıtlar ortaya koyulmuştur. Özel olarak dizayn edilen sürekli sistemde kaymak yüzeylerine 0.855-26.732 kJ/m2 doz aralığında (iki farklı yükseklik (7.5 ve 20 cm) ve 7 farklı bant hızında (0.2-4.0 m/dk)) UV-C ışık uygulaması gerçekleştirilmiş ve örneklerin bileşim, lipid oksidasyon düzeyi (tiyobarbitürik asit reaktif madde (TBARS) ve peroksit değeri), renk, asit değeri, sertlik ve duyusal özellikleri belirlenmiştir. Bu aşamada dozların kalite ile ilişkisi ortaya koyulmuştur. Daha sonra, 3 farklı dozda (1.076, 2.174 ve 4.427 kJ/m2) (20 cm yükseklik, 3.2, 1.6, 0.8 m/dk bant hızı) UV-C ışık uygulaması yapılmış ve depolama süreci takip edilmiştir. UV-C ışık uygulaması, kaymak örneklerinin bileşimini ve sertlik indeksi değerlerini etkilememiştir. Buna karşın, UV-C ışık dozunun artmasıyla lipid oksidasyon seviyesi, asit değeri ve b* değeri artmıştır. Yüksek UV-C ışık dozlarında (≥ 4.427 kJ/m2) yabancı lezzet algılanmış ve buna bağlı olarak tüm izlenim puanlarında düşüş meydana gelmiştir. 7.5 ve 20 cm yükseklik ile 1.6 m/dk ve daha yavaş bant hızlarında (≥ 2.174 kJ/m2) UV ışık uygulamaları kabul edilebilir duyusal özellikler göstermiştir. Depolama süresince UV ışık uygulama dozuna paralel olarak örneklerin peroksit ve TBARS değerleri artmıştır. Ayrıca, depolama süresince örnekler fotoğraflanarak yüzeyde küf gelişimleri takip edilmiş ve kontrol örneklerinde yüzeyde küflenme daha erken ve daha fazla sayıda gerçekleşmiştir. Çalışmada, UV-C ışık teknolojisinin kaymakta yüzeyde küf gelişimini engellemek için kullanılabileceği, ancak doz seçiminde yağ oksidasyonunun dikkate alınması gerektiği sonucuna varılmıştır. Sürekli sistemde UV-C ışık uygulamasının sanayiye/üretim hattına adapte edilebilir olması sektör açısından avantaj sağlayacağı düşünülmektedir. Ayrıca ayarlanabilir bant hızı ve ışık yüksekliği sayesinde üretim hızına kolaylıkla uyum sağlayacaktır. Üretim hattına dahil olmasının bir diğer avantajı ise UV-C uygulama sonrası bulaşma riskinin en aza indirilmesidir. Çünkü ambalajlama aşamasından hemen önce kurulacak olan bir UV-C sisteminden geçen ürünler doğrudan ambalajlama aşamasına geçeceğinden bulaşma riski azalmış olacaktır.Turkish Cream (Kaymak) has been produced in our country with the traditional method for many years, it is produced directly from cream in dairy enterprises in recent years. In traditional kaymak production, the kaymak surface is quite open to contamination during the gathering and hardening and packaging of the kaymak. UV light technology is used for microbial inactivation in foods. However, it is important to protect the physical, chemical, and sensory quality of the product while providing microbial inactivation. In this study, the effect of UV light technology on kaymak quality was investigated and the limitations were revealed. In a specially designed continuous system, UV-C light was applied to kaymak surfaces at a dose range of 0.855-26.732 kJ/m2 (two different heights (7.5 and 20 cm) and 7 different band speeds (0.2-4.0 m/min)). The composition, lipid oxidation level (thiobarbituric acid reagent (TBARS) and peroxide value), color, acid value, hardness and sensory properties of the samples were determined. At this stage, the relationship between doses and quality has been investigated. Then, UV-C light was applied to the samples in 3 different doses (1.076, 2.174 ve 4.427 kJ/m2) (20 cm height 3.2, 1.6, 0.8 m/min band speed) and the storage process was followed. UV-C light treatment did not affect the composition and hardness index values of the kaymak samples. On the other hand, with increasing UV-C light dose, lipid oxidation level, acid value and b* value increased. Foreign flavor was perceived at high UV-C light doses (≥4.427 kJ/m2) and accordingly, total impression scores decreased. UV light applications at 7.5 and 20 cm height and 1.6 m/min and slower band speeds (≥2.174 kJ/m2) showed acceptable sensory properties. Peroxide and TBARS values of the samples increased in parallel with the UV-C light application dose during storage. In addition, mold growth on the surface was followed by photographing samples during storage. Molding on the surface occurred earlier and more count in the control samples. As a result, it was concluded that UV-C light technology can be used to prevent mold growth on the kaymak surface, but lipid oxidation should be taken into consideration in dose selection. The fact that UV-C light application in the continuous system can be adapted to the industry/production line is considered to be an advantage for the sector. In addition, it will easily adapt to the production speed thanks to its adjustable band speed and distance (as hight) between light and the sample. Another advantage of being included in the production line is that the risk of contamination after UV-C application is minimized. Because the products that pass through a UV-C system to be installed just before the packaging stage will go directly to the packaging stage, the risk of contamination will be reduced

No full textBu çalışmanın amacı; Kanser Erken Teşhis, Tarama ve Eğitim Merkezleri’nin (KETEM) kurulmasından sonra, Türkiye’de yazılmış olan ve Yükseköğretim Kurulu (YÖK) ulusal tez merkezi veri tabanında yayımlanan, KETEM tarama terimi yazılarak ulaşılan lisansüstü tez çalışmalarının değerlendirilmesini kapsamaktadır. Aramalar sonucu 2008-2024 yılları arasında yazılmış olan 70 adet tez bulunmuştur. Bulunan 70 adet tezin incelenmesi sonrası; bunların 63 tanesinin KETEM ile alakalı olduğu saptanmıştır. Çalışmanın örneklemini 2008-2024 yılları arasında yazılmış KETEM konulu 63 tez oluşturmaktadır. Lisansüstü yazılmış olan tezlerden 1 tanesinin erişim izni bulunmamaktadır fakat ön izlemeden alınan bilgiler doğrultusunda çalışmaya dahil edilmiştir. İncelemeler sonrasında KETEM’in, çeşitli lisansüstü türlerde kullanıldığı görülmüştür. İncelemelerde en fazla Aile Hekimliği Anabilim Dalında çalışmalar yapıldığı gözlenmiştir. KETEM her ne kadar incelenen tezlerde geçiyor olsa da KETEM konu olarak seçilmekten daha ziyade KETEM’e başvuran hastalar veya KETEM’de yapılan taramalar veri kaynağı olarak kullanılmıştır. KETEM’in işleyişi ve KETEM hakkında detaylı bilgilendirme yapan çok az sayıda tez olduğu görülmüştür. Bu proje ile bundan sonra yapılacak olan çalışmalar için KETEM kavramı, KETEM’in işleyişi ve çalışma prensipleri ortaya konulmaya çalışılmıştır.The purpose of this study; it covers the evaluation of postgraduate thesis studies written in Turkey after the establishment of Cancer Early Diagnosis, Screening and Education Centers (CEDSECs) and published in the Council of Higher Education (CoHE) national thesis center database, which can be accessed by typing the KETEM screening term. As a result of the searches, 70 theses written between 2008-2024 were found. After examining the 70 theses found; it was determined that 63 of them were related to KETEM. The sample of the study consists of 63 theses on KETEM written between 2008-2024. One of the graduate theses did not have access permission but was included in the study based on the information obtained from the preview. After the examinations, it was seen that KETEM was used in various types of postgraduate studies. In the examinations, it was observed that the most studies were carried out in the Department of Family Medicine. Although KETEM is mentioned in the theses examined, patients applying to KETEM, or scans performed in KETEM were used as data sources rather than KETEM being chosen as the subject. It has been observed that there are very few theses that provide detailed information about KETEM's functioning and KETEM. With this project, the concept of KETEM, the functioning of KETEM and its working principles have been tried to be revealed for future studies
Europeanization integration and identity: A social constructivist fusion perspective on Norway
No full textThis book analyses how domestic and European structures impact on national actors' identities, interests and foreign policy practices. Employing Norway as the case study area, the author uses this nation as an example to assess Europeanization and identity politics across the European Union (EU).Utilising an original and innovative approach called 'social constructivist fusion perspective', the author addresses Europeanization across several key factors. The author assesses the influence of the EU on 'half-way member countries', and the impact of identity politics and domestic structures, which factors contribute to or hinder Europeanization, and attempts to empirically measure Europeanization at the actor level. It analyses the impact of domestic and European structures on the identities, interests, attitudes and foreign policy practices of the Norwegian policy-makers. Whilst contributing to knowledge and literature on how constructivist approaches can be utilized in empirical studies of political elites, this book goes beyond theory to demonstrate that Europeanization is not only institutional, and provides evidence of the influence of identity politics.Europeanization, Integration and Identity will be or interest to students, scholars and policy-makers in the field of European Union politics, international relations, social constructivism and Scandinavian politics. © 2012 Gamze Tanil
From mythological ages to Anthropocene: Nature and human relation: Mitolojik çağlardan Anthropocene: Doğa ve insan ilişkisi
No full textEnvironmental pollution, global warming, reduction of living resources, extinction of species, the energy problem, urbanization, deforestation and ecology issues and so on are the important agenda topic of the mankind in the 21st century. While fighting with these problems, mankind cannot produce realistic and durable solutions, especially in advanced societies. Adding a mental depth, ethical perspective, and the basic mankind traditions to the contribution of the mankind to the ecological problems through his mind will provide realistic and permanent results. For this reason, we will first examine the concepts of myth and nature and their relation to each other. In this study, we will address the relationship between nature and mankind with a mythological perspective from mythological ages to today's Anthropocene era- hunting-gathering, agriculture, urbanization, industrialization periods - and make comparisons and draw conclusions. In addition, we will examine the messages of the myths to identify the historical ecological perspective of Turkish society and produce solutions to the main ecological problems of today. We will examine Book of Dede Korkut and the Duha Koca oğlu Deli Dumrul, which is one of the 12 stories in that Book in terms of nature and human relations, which express the perspective of Oghuz Turks life and point of view to the world, whose situate at the east of Anatolia between 12th and 13th century. Starting from the myths, we will compare the contemporary ecological perspectives –deep, superficial, social ecology etc.– with the relation of people with nature in the mythological eras. In our study, it is also possible to find answers to these questions with Duha Koca Oğlu Deli Dumrul Tale: "How is the nature-human relationship in the mythical period?", "How did the mythological age man approach the present state of the problems we are experiencing today?", "What are the basic elements of man in relation to nature?", "Is it possible to reduce human harm to nature and to bring ethical values away from personal interests in relation to nature?", "How is an effective nature education provided?"

Özet
21. yüzyılda, çevre kirliliği, küresel ısınma, yaşam kaynaklarının azalması, canlı türlerinin yok olması, enerji sorunu, kentleşme, ormansızlaşma vb. ekoloji sorunları insanlığın en önemli gündem maddelerinden birkaçıdır. Bu problemlerle mücadele ederken insanlık, - özellikle de gelişmiş toplumlar- gerçekçi ve kalıcı çözümler üretememektedir. İnsanoğlunun aklıyla ekolojik problemlere sunduğu katkıya, ruhsal bir derinlik, etik bir bakış açısı ve temel insanlık geleneklerini eklemek, gerçekçi ve kalıcı sonuçlar ortaya koyacaktır. Bu nedenle, öncelikle mit ve doğa kavramlarını ve bu kavramlarının birbirleri ile olan ilişkisini inceleyeceğiz. Daha sonra çalışmamızda, mitolojik çağlardan günümüz Anthropocene çağına kadar – avcılılık-toplayıcılık, tarım, kentleşme, endüstrileşme dönemlerindeki – doğa ve insan ilişkilerini, mitolojik bir bakış açısıyla ele alacak, karşılaştırmalar ve çıkarımlar yapacağız. 12.-13. yüzyıllarda Anadolu’nun doğusundaki Oğuz Türklerinin yaşamını ve dünyaya bakış açısını arı bir dille anlatan Dede Korkut Destanını ve Destandaki on iki hikâyeden biri olan Duha Koca oğlu Deli Dumrul’u, doğa ve insan ilişkileri bağlamında inceleyeceğiz. Ayrıca Türk toplumunun tarihsel ekolojik bakış açısını belirlemek ve bugünün temel ekoloji sorunlarına çözüm üretmek için de mitlerin bize sunduğu mesajları ele alacağız. Mitlerden yola çıkarak bugünün ekoloji anlayışları – derin, sığ ve toplumsal ekoloji vb. – ile mitolojik çağlardaki insanların doğayla olan ilişkilerini karşılaştıracağız. Çalışmamızda ayrıca Duha Koca Oğlu Deli Dumrul Hikâyesi ile, “Bugün yaşadığımız ekolojik sorunların benzerlerine mitolojik çağın insanı nasıl yaklaşmıştır?”, “İnsanın doğa ile olan ilişkisindeki temel unsurlar nelerdir?”, “İnsanın doğaya verdiği zararı azaltmak ve doğayla olan ilişkisinde kişisel çıkarlardan uzak, etik değerler ortaya koymak mümkün müdür?”, “Etkili bir doğa eğitimi nasıl sağlanır?” sorularına da cevaplar bulmak mümkündür

No full textGültekin, Gamze (Dogus Author) -- 26.06.2018 tarihine kadar kullanımı yazar tarafından kısıtlanmıştır.Bu çalışmanın amacı Karanlık Kişilik Özelliklerinin kişilerarası bağlamda keşfedilmesi ve kişilerarası risk kavramı altında bulunan, etik risk alma, sosyal risk alma, statü odaklı risk alma değişkenleriyle ilişkisinin incelenmesidir. Buna ek olarak, Karanlık Kişilik Özelliklerinin kendini sunma ve öz farkındalık duyguları olarak adlandırılan benlik kavramları ile ilişkisi incelenmektedir. 171 kadın 175 erkek olmak üzere toplam 346 katılımcıdan oluşmaktadır. Çalışmada kullanılan materyaller, demografik bilgi formu, Statü odaklı risk alma ölçeği, Alan odaklı risk alma ölçeği, Revize edilmiş Kendini Sunma Ölçeği, ve Uygunluk Endişesi Ölçeği'dir. Çalışmada kullanılan analizler doğrulayıcı faktör analizi, korelasyon analizi ve çoklu lineer regresyon analizidir. Çalışmada bulunan temel sonuçlara göre her Karanlık Kişilik Özelliği statü-amaçlı risk alma ile pozitif yönde ilişki gösterirken sosyal risk alma ile negatif ilişki göstermektedir; fakat sadece Makyavelizm ve psikopati etik risk alma ile pozitif ilişki göstermektedir. Kendini sunma davranışı hem açgözlü hem de koruyucu stillerle narsisizm ve Makyavelizm ile pozitif yönde ilişki gösterirken psikopati sadece koruyucu stil ile pozitif ilişki göstermiştir. Öz farkındalık duygularıyla olan ilişkiye bakıldığında ise, sadece narsisizm utanç ile negatif ilişki gösterirken, tüm karanlık kişilik özellikleri suçlulukla negatif yönde ilişki göstermiştir. Kibirli gururla olan ilişkide hem Makyavelizm hem psikopati pozitif yönde ilişki gösterirken, gerçekçi gururda ise sadece psikopati negatif yönlü ilişki göstermiştir. Bulgular ilgili literatür çerçevesinde tartışılmıştır.The aim of this study is to examine Dark Triad personality traits in interpersonal context by examining their relationship with ethical risk taking, social risk taking and status-driven risk taking which are conceptualized as interpersonal risk taking. Moreover, Dark Triad's relationship with self-concepts is examined, namely self-presentation styles and self-conscious emotions. 346 participants, 171 men and 175 women participated in this study. The questionnaire used in the present study included demographic questions, Short Dark Triad Scale, Status-driven Risk Taking Scale, Domain-specific Risk Taking Scale, Revised Self-Monitoring Scale and Concern for Appropriateness Scale. Confirmatory Factor Analysis, Correlation Analysis and Multiple Linear Regression Analysis were conducted. The main results found in the study were that each Dark Triad trait was positively correlated with Status-driven risk taking and social risk taking, however only psychopathy and Machiavellianism showed positive relationship with ethical risk taking. For the self-presentation, narcissism and Machiavellianism were positively related with both acquisitive and protective styles; psychopathy was only related with protective self-presentation style. For the self-conscious emotions, only narcissism was negatively related with shame; all facets of dark triad were negatively related with guilt. For the hubristic pride, both Machiavellianism and psychopathy were related positively; for the authentic pride only psychopathy showed negative relationship. Results are discussed in the light of literature
Activities and Opinions of Science Teacher Candidates on Ecological Citizenship
No full textTeachers undertake important tasks regarding awareness of the environment and raising ecological citizens. In particular, science courses include ecological issues, and science teachers are more responsible for being practitioners of these courses. The purpose of this study is to determine pre-service science teachers' views on ecological citizenship, rights of nature, ecological constitution, participation, responsibility, sustainability, rights and justice, which are the features of ecological citizenship. In line with this purpose, the study uses phenomenological design, which is a qualitative research method. The study group of the research is composed of 21 science teacher candidates, except for senior year students, attending the education faculty of a state university in a large city in the Black Sea region in 2020-2021 academic year. Descriptive analysis method was used in the analysis of the interviews. According to the findings of the study, science teacher candidates thought individuals must first be aware of nature rights and their responsibilities to nature in order to qualify as ecological citizens. It was found that teachers thought all the creatures living in nature, just like humans, have the right to live. They also thought that the protection of nature should be secured by certain laws and rules. In this respect, environmental education programs applied from pre-school to university are recommended to be reexamined in terms of ecological citizenship

The effect of copper coated metal hydride at different ratios on the reaction kinetics
No full textIn this study, the process parameters that affect the improvement of hydrogen storage material properties were investigated. In order to accelerate the hydrogen charge/ discharge processes and to obtain the required hydrogen at the desired flow rates in a short time, the thermal conductivity of the storage materials has been improved, and density analyses have been made. The ideal grinding time has been determined for the LaNi5 material. Within the scope of the experimental studies, the thermal conductivity coefficients of LaNi5 coated with copper and LaNi5 ground for 5 h and coated with copper were increased by 500-750%, and the copper plating ratios were optimized. The materials obtained were characterized by XRD, SEM, and their density was measured with the Helium Pyknometer device and their thermal conductivity coefficients with the Hot Disk Thermal Constants Analyzer. In addition, the hydrogen storage of materials with increased thermal conductivity was investigated experimentally in the metal hydride reactor at the determined pressure. In the study, it was seen that the storage material coated with copper increases the heat transfer, reduces the hydrogen charging time in the metal hydride reactor, and increases the stable discharge time. & COPY; 2022 Hydrogen Energy Publications LLC.
